Filled May 15, 1962, Ser. No. 194,761 4 Claims. (Cl. 15-552) This invention relates to a brush attachment for a pressurized container or other discharging or ejecting device and more particularly to a brush having a hollowed out center to permit discharging or ejecting the medium to be applied by thebrush.

The prior art illustrates various devices in which a brush is utilized as a part of the device. For example, in Patent 2,849,737 there is a lather applicator in which the brush is a part of the cover that is snapped over the pressurized can and in Patent 2,764,772 there is similarly illustrated a brush with a valve and dispensing tube that is secured to the top of a pressurized dispenser. And in Patent 2,756,908 there is illustrated a brush as a part of an attachable head for a pressurized soap container, the attachable head being secured to said container. The prior art also illustrates various brushes that are attached or combined with a collapsible tube for dispensing the medium into the brush in use such as Patent 2,505,441 which illustrates a fountain brush attachment in which the brush is secured to a head that is in turn threadably secured to a collapsible tube. Patent 1,674,510 illustrates a similar arrangement of a brush as a part of a head that is threadably secured to a collapsible tube. And Patent 2,750,615 illustrates a further example of a brush mounted to a head of a shaving brush where the head is threadably secured to a dispensing handle.

This invention is specifically drawn to a hollow center brush that may be utilized with any pressurized container as a slip on attachment. The brush is formed with a base having a central aperture into which any one of a plurality of rubber or other resilient material in the form of a grommet may be inserted. In each instance the grommet is provided with a central aperture to fit one or more of the standard shapes of ejecting tubes now found on the various pressurized dispenser. A further form of this invention is to provide a brush attachment in which the base of the brush is provided with a small tube that may be inserted into the center of anyof the ejecting tubes of the known pressurized containers.

It is an object of this invention to provide a brush with a hollow center mounted to a base element in which the base element is provided with a resilient frictionally grip ping grommet having an aperture to fit an ejecting tube of a particular pressurized container.

A further object of this invention is to provide a brush with a hollow center mounted to a base element in which the base element is provided with a resilient frictionally gripping grommet having an aperture to frictionally grip the ejecting tube of a particular pressurized container.

A still further object of this invention is to provide a brush with a hollow center mounted to a base element in which the base element is provided with a resilient frictionally gripping grommet having an aperture to frictionally grip the ejecting tube of a particular pressurized 3,164,355 Patented Jan. 12, 1965 surized container.

A further object of this invention is to provide a brush with a hollow center mounted to a base element inwhich the base element is provided with a resilient frictionally gripping grommet and in which the grommet is provided with an extended tube that will fit into the ejecting tube of a particular pressurized container.

A still further object of this invention is to provide a brush having a particular configuration for a specific use mounted to a base element in which the base element is provided with a resilient frictionally gripping grommet having an aperture to fit an ejecting tube of a particular pressurized container.

Other objects of this invention shall be apparent by reference to the accompanying detailed description and the drawings in which FIG. 1 illustrates a slip on shaving brush mounted on a pressurized container,

FIG. 2 is a plan view of the brush in its mounted position,

FIG. 3 illustrates one form of mounting grommet,

FIG'. 4 illustrates a further form of mounting grommet,

FIG. 5 illustrates a still further form of'mounting grommet,

FIG. 6 illustrates a still further grommet,

FIG. 7 illustrates a still further grommet,

FIG. 8 illustrates a further embodiment of this invention,

FIG. 9 illustrates a further embodiment of this invention,

FIG. 10 illustrates a further embodiment of this invention,

FIG. 11 illustrates a still further embodiment of this invention, and

FIG. 12 illustrates a further embodiment similar to FIG. 2.

Referring to FIG. 1 there is illustrated a pressurized container 10 such as that presently used for dispensing shaving cream. All of the pressurized containers are provided with an ejecting or extruding tube 11 but in View of the fact that the containers are manufactured by various different manufacturers the tubes 11 take various configurations and sizes. Thus no single fitting may be provided to fit all of the presently known tubes 11. Thereform of mounting form of mounting fore although this invention is primarily concerned with a small brush 12 generally in the form of a shaving brush in which there is a hollowed out center 14 and a base element 15, the base element 15, FIG. 2, is provided with a central aperture 15 into which a resilient frictionally gripping grommet 17 may be pressed. Grommet 17 is provided with a central aperture 18. The base 15 of the brush 12 may also be provided with a rounded face 20 to fit-the general configuration of most of the pressurized containers. Or face 20 may be shapedto the configuration of the pressurized container whether flat, round, octagonal, etc. and as a further embodiment of this invention a resilient band 21 may be attached at one side of base 15 at a point 22 to extend around to the other side of base 15 at a point 23. This resilient band provides a means to retain base 15 in a tight fitting relationship with C9 the top of the container M. It is apparent with this type of personalized brush 12 that a single container lilmay be utilized by more than one person whether in the home or elsewhere permitting each person to easily slip his or her brush 12 upon the ejecting or extruding tube 11. It is also apparent that with a replaceable grommet 17, that is, with each brush 12 there are provided a plurality of grommets, FIGS. 3 through 7, all of the grommets frictionally fitting the base 15 within the aperture 16. However the grommets are provided with difi'ercnt types of central apertures showing a around aperture 18A, FIG 3, an oval shape aperture 1313, FIG. 4, a rectangular aperture 18C, FIG. 5, a square aperture 18D, FIG. 6, and a half round aperture 1815, FIG. 7. Thus a brush 12 with the various grommets may be easily and quickly adapted to any of the presently known pressurized shaving cream dispensers.

Although the prior embodiment has referred to specifically a shaving cream brush it is apparent that the form of brush may be varied to utilize a pressurized container and brush for other purposes without departing from this invention. The brush 12 may be formed as a much shorter and stiller type of bristle brush for cleaning purposes and as in the prior embodiment a plurality of brushes 12 may be provided for cleaning purposes, that is, the brushes may vary from a very soft type of brush for delicate material to a fairly stiff type of brush for coarse material and as in the prior embodiment the cleaning fiuid or cream as the case may be, may be easily and quickly ejected into the brush for cleaning purposes. Also with the replaceable brushes there is no danger of discoloring, that is if a brush. has been used on one color material and there is any tendency for the color to run a different brush may be quickly and easily mounted to insure a cleaning without carrying over dirt or color from the previous cleaning. A further embodiment of the cleaning device is illustrated in FIG. 12 in which the base 15 supports a sponge pad 25. In some instances the sponge pad provides a better cleaning medium than a brush, the sponge pad otherwise performing exactly the same function as brush 12. In a cleaning operation brush 12 or sponge pad may be attachable to any of the known dispensers for cleaning or for spot removal.

Brush 12 may also be provided with a base 15 to fit a pressurized container of nail polish. In this instance brush 12 may be formed according to FIG. 9 with the brush pointed and base 15A formed slightly different to retain the bristles in the formation as illustrated, all other details of base 15A being similar to base 15 of FIG. 2. It is also apparent that brushes 12 or pad 25 may be similarly utilized for medical purposes, that is, with a pressurized container of alcohol or any medicinal solution whether it be a liquid or cream may be easily dispensed through the brush 12 or pad 25 for application to the external portions of the person being treated. it is quite apparent that in this instance the brush 12 or pad 25 must be sterilized and may be used only for that particular person and in some instances only that one application after which the brush or pad must be dispensed thus this invention lends itself to an easily dispensable applicator for medicinal brushes.

Similarly the brush 12 or pad 25 may be quickly and easily attached to a soap dispenser which would in form be similar to that illustrated in FIG. 1. In this instance the liquid soap is not provided as a lather but rather the pad or brush will produce the lather only in the rapid movement with the soap that is dispensed in a bath operation. Again in this embodiment it is to be noted that each brush or pad may be personalized so that although the soap dispenser may be used by more than one each one will utilize his or her own brush or pad.

A further application of brush 12 or pad 25 is to mount base 15 on a pressurized shoe polish dispenser. As in one of the previous embodiments the brush may be formed of the proper texture for this particular purpose Cir 4 thus easily and quickly spreading the liquid or cream that is dispensed and it is also to be noted that the brush may be quickly and easily washed out after use and may be used for different colored polishes as desired. Or a plurality of brushes may be provided but in each instance the brush or pad should be cleansed after use.

A still further use of this invention is to provide a ressurized container of paint or coloring material with a similar brush attachment 12. In this instance the brush may take the form as illustrated in FIG. 2 or the form as illustrated in FIG. 9 or any other configuration as desired and in a still further embodiment the brush 12 may be mounted on an elongated flexible tube 26, the tube in turn being frictionally mounted over the dispensing 0r ejecting tube 11 of the pressurized container. In this particular embodiment the paint or coloring material is not actually sprayed onto the picture or surface on which the paint or color is to be applied rather the pressurized container is a controllable supply of paint or coloring material in which the valve of the container may be operated to supply the desired coloring material when needed and in the quantity needed. A further embodiment of the invention with relation to FIG. 10 is illustrated in FIG. 11 in which tube 26 is also provided with a guard 27 surrounding brush 12. In this instance tube 26 is a very short tube and the paint or coloring material may be sprayed directly through tube 26 and brush 12 thus the guard 27 is in the form of a protector to prevent the spattering of the liquid when applied.

Referring to FIG. 8 there is illustrated a further embodiment of this invention in which brush 12 is similarly mounted on a base 15 and in which the grommet takes an elongated form 17A, that is, one end of grommet 17A will lit the aperture 16 of base 15 and frictionally grip said base as in the previous embodiments. However, the other end of grommet 17A is elongated and reduced to fit into the inside diameter of the extruding or expelling tube 11 and frictionally grip said tube thus providing an easily inserted brush to be used as already described in the previous embodiments.

Although this device has been described as a personalized slip on easily mounted or removed brush for a pressurized container, the brush in its various forms may also be applied to any dispensing container not necessarily pressurized for example, a collapsible tube permits its contents to be easily and quickly ejected through a brush of this type. Or a plastic container having flexible walls to permit squeezing the container to eject the fluid or cream contents may be similarly used without departing from the spirit of this invention and although this device has been described in conjunction with a shaving operation, a cleaning operation or washing, a paint operation, a cosmetic operation, or for medicinal purposes it may also be used for any other practical purpose in a similar manner without departing from the spirit of this invention and this invention shall be limited only by the appended claims.
